head to head
Sniper Elite 4 asks more than Grand Theft Auto: San Andreas, and the gap is execution.

Optimization · Practiced Mastery
A sprawling open-world crime epic with RPG-style character stats across a whole state.

Execution · Practiced Mastery
Balancing ballistics execution with patrol timing to eliminate targets without triggering coordinated alerts.
Grand Theft Auto: San Andreas leans Optimization (Practiced Mastery); Sniper Elite 4 leans Execution (Practiced Mastery).
Sniper Elite 4 leans clearly harder on execution.
Grand Theft Auto: San Andreas
Flying school and drive-bys need decent hands
Sniper Elite 4
Long-range ballistics, bullet drop, and wind compensation are the core demand
Sniper Elite 4 leans a little harder on reads, though the gap is small.
Grand Theft Auto: San Andreas
Gang AI is scripted, never adaptive
Sniper Elite 4
Axis soldiers follow scripted patrol cycles without modelling the player
Sniper Elite 4 leans a little harder on variance, though the gap is small.
Grand Theft Auto: San Andreas
Territory wars and traffic add light randomness
Sniper Elite 4
Wind direction and enemy patrol timing add first-run uncertainty
Same score on optimization - which means the number cannot separate them. The difference is in what each one asks of you.
Grand Theft Auto: San Andreas
Stats, gym, weapon skill, and routes reward systematic play
Sniper Elite 4
Synchronised shot timing and route planning reward methodical preparation
A matching score does not mean a matching test. Two games can both sit at 10 on execution and demand completely different things of you - which is why the reasoning above matters more than the number beside it.
